UNITED STATES CHARLES EDOUARD JEANNOTTE, OF MONTREAL, QUEBEC, CANADA.

RADIATOR.

Application filed January 16, 1919.

To all whom t may concern.'

Be it known that I, CHARLES EDOUARD .,EANNoTTn, residing at 99 Parc avenue, Montreal, Quebec, Canada, have invented certain new and useful Improvements in Radiators; and I do hereby declare that the following is a full, clear, and exact description of the same.

This invention relates to improvements in radiators; and the primary object is to provide a radiator having a large heating surface. A further object is to provide an article or' this description which will be cheap, simple of construction and easily heated. Another object is to have an even water circulation therethrough.

The invention will be understood with the aid ci the accompanying drawings in which Figure 1 is a side elevation of the radiator.

Fig'. 2 is a longitudinal section through one of the radiator sections.

Fig. 3 is a cross section on line A-A of Fig. Q.

Like numerals of reference indicate coro responding parts in each figure.

The radiator illustrated in Fig. 1 of the drawings, consists of a series of vertical sections l, preferably oil cast iron, having a hollow or inner open portion 2. 3 is a circumferential vertical water column formed within the walls of the section 1. Adjacent each end of the section l, is provided an enlarged annular cavity 4; communicating with the 5 is an integral outwardlyprojecting boss preferably provided with Specification of Letters Patent.

Patented June 8, 1920.

Serial No. 271,544.

an internal screw thread to receive one end. of a nipple 6, the other end of which is received in the boss 5 on an adjacent section 1, thus serving asa connection for the water jackets of the adjacent units. One of the bosses 5 in each end section is preferably closed by a threaded plug 7. 8 indicates the water inlet pipe which is provided with the usual valve 9. 10 is the return pipe.

A feature of this invention is the annular enlarged portion 4: provided in each section adjacent the water inlet and outlet, whereby the water, during its flow through the radiator and piping, will not be forced through any reduced opening but will have a substantially uniform passage.

What I claim is A radiator section comprising an external tube, an internal tube formed integral with the external tube, said tubes joining at the top and bottom and spaced from each other to form a narrow circumferential water jacket between them, the external tube having an annular enlargement adjacent each end of the water jacket to form an enlarged pocket at each end of the water jacket, and a boss at each side of each enlargement having openings therein to form inlets and outlets for the water. y
